Java code review

Each new version of IntelliJ IDEA extends its static code analysis capabilities, and this version is no exception. In addition to a series of improvements, 2020.1 also adds new code review capabilities. Examples include checking capitalization in SimpleDateFormat schema, analyzing use cases in date formatting, finding additional redundant method calls, and reporting and recommending the elimination of unnecessary escape characters in string literals.

Download JDK from IDE

Starting with IntelliJ IDEA 2020.1, you can download and configure JDK directly from IDE when you create and configure a project. If you open a downloaded project, IDE checks to see if the machine has installed the JDK configured for the project, and prompts you to download if it is missing.

LightEdit mode

LightEdit mode allows users to quickly modify stand-alone files in the window of a class text editor without creating or loading projects. You can open files in LightEdit mode through the command line, the welcome interface of IDE, or the file manager of the operating system. Use the "Open File in Project" intention (Alt+Enter) to switch from LightEdit mode to full mode.

Zen mode (Zen mode)

Zen mode eliminates possible distractions and helps developers focus entirely on the code. In essence, this new mode combines do not Disturb mode and full screen mode, so you don't have to enable or disable them every time you want to enter or exit them. To enable Zen mode, jump to View | Appearance | Enter Zen Mode, or select (Ctrl+ `| View mode | Enter Zen Mode) from the Quick switching Scheme pop-up window.

Data flow analysis assistance function

IntelliJ IDEA 2020.1 adds data flow Analysis Assistance (Dataflow analysis assistance) to the debugger, which predicts and displays possible exceptions and conditions that are always true / false based on the current state of program execution.

When we debug the Java code and reach the breakpoint, IDE runs the data flow analysis based on the current state of the program and shows us what happens next before the code executes to that breakpoint:

Install Git from IDE

In IntelliJ IDEA 2020.1, users no longer need to manually install Git in advance. When cloning a Git repository, IDE looks for the Git executable in the machine, and if it cannot find it, it downloads it and sets it up.

JetBrains Mono

A font launched by jetbrains a few months ago is now the default font for IntelliJ IDEA and a new font designed for coding.

Unified IntelliJ Light theme

IntelliJ IDEA 2020.1 adopts a new default Light theme and is unified across all different operating systems. You can roll back to the old topic via View | Quick Switch Scheme | Theme.
